Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Battery Inspection and Replacement

Sub-step 1: Remove the battery from the vehicle.
- Tools required: Socket set, wrench.
Sub-step 2: Clean battery terminals and connectors with a wire brush.
Sub-step 3: Test the battery with a multimeter. Replace if voltage is below 12.4 volts.
Sub-step 4: Install a new battery if necessary, ensuring terminals are tight and free of corrosion.

3. Starter Motor Testing and Replacement

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Check the starter motor's electrical connections for tightness and corrosion.
Sub-step 3: Use a multimeter to check voltage at the starter during cranking. Replace if voltage is low.
Sub-step 4: If necessary, remove the starter motor.
- Tools required: Socket set, torque wrench.
Sub-step 5: Install the new starter motor, ensuring proper alignment and torque specifications are followed (typically 20-30 Nm).

4. Fuel System Check

Sub-step 1: Inspect the fuel pump relay and fuse for functionality.
Sub-step 2: Check fuel pressure with a fuel pressure gauge; replace the fuel filter if pressure is low.
Sub-step 3: Ensure fuel injectors are clean and operating correctly.
